This brief defines edge computing and explains why it has become a critical component of modern IT architectures. It describes the edge as the place where data is created, processed, and acted upon close to users, devices, and sensors, rather than being sent to centralized data centers or clouds. The document highlights key drivers such as latency-sensitive applications, massive data volumes, bandwidth constraints, and real-time decision-making. Use cases include manufacturing, retail, healthcare, transportation, and smart cities. By processing data locally and integrating with cloud and on-premises systems, edge computing improves performance, resilience, security, and operational efficiency.
